8 / 9 page LA72914V No.A1859-8/9 [De-modulation block] • Demodulate audio signal from modulated audio signal. • FM-Audio signal is input from pin5. Go through 4.5M-Trap-filter or 6.5MHz-Trap-filter and AGC go to demodulator. After demodulator go to De-emphasis circuit. After de-emphasis circuit signal is output pin7. Pin7 signal is charge to DC bias for coupling capacitor at pin8. Audio signal from pin8 go to 6dB AMP then output from pin9. (Door-phone application, there are two FM carrier. In this case we recommend add BPF before pin5 FM-Audio signal input.) • 4.5M/6.5MHz-Trap-filter: Internal Trap-filter is change for pin6 mode control. (If modulator frequency is 4.5MHz, then internal Trap-filter is 4.5MHz.) • AGC: After AGC level is control about 0.3Vp-p. After AGC signal go to pin12 FM-monitor and de-modulator. • De-emphasis circuit: The pin7 owns an De-emphasis characteristic which connected capacitor. Recommended value = 10nF. • Output signal level: If input FM signal deviation is ±25 kHz, then output signal level is 1Vp-p (TYP) from pin9/ (Load resistance: 10k Ω at 1 kHz.)
